Re: extracting a substring

You don't need a regex for this, as long as the prefix and suffix are fixed lengths, the following will do: >> "a53bc_531.txt"[6:-4] '531' >>> "a53bc_2285.txt"[6:-4] '2285' [EMAIL PROTECTED] wrote: > Hi, > I have a bunch of strings like > a53bc_531.txt > a53bc_2285.txt > ... > a53bc_359.txt >

extracting a substring

Hi, I have a bunch of strings like a53bc_531.txt a53bc_2285.txt ... a53bc_359.txt and I want to extract the numbers 531, 2285, ...,359. One thing for sure is that these numbers are the ONLY part that is changing; all the other characters are always fixed. I know I should use regular expressions,
